Front

What is crossing over and when does it occur?

Back

Crossing over is the exchange of genetic material between homologous chromosomes during Prophase I of meiosis.

Front

What is the significance of crossing over in meiosis?

Back

It increases genetic diversity in gametes.

Front

What are homologous chromosomes?

Back

Chromosomes that are similar in shape, size, and genetic content, one inherited from each parent.

Front

What are sister chromatids?

Back

Identical copies of a chromosome, connected by a centromere, formed during DNA replication.

Front

What is cytokinesis?

Back

The process that divides the cytoplasm of a parental cell into two daughter cells after mitosis or meiosis.

Front

What happens during Prophase I of meiosis?

Back

Chromosomes condense, homologous chromosomes pair up, and crossing over occurs.
